Good evening everyone,
I am trying to create a sensor with which I can record how many devices are registered in my guest WLAN. I have already realised that I can find the attribute SSID with the corresponding WLAN name in the device_tracker entities, but so far I don’t see a way to count them.
I would like to have a sensor that gives me the number of devices in the guest WLAN.
Does anyone have an idea?
Many thanks in advance!
